Filed: 1983-04-21
Abstract: PURPOSE:To provide an electrode for welding a lead wire which can weld the lead wire with the smaller diameter of a groove through which the lead wire passes than in the prior art, eliminates the reactive current making no contribuion to welding and improves the accuracy in the welding position by forming insulating layers on the opposed surfaces of a pair of electrodes and the groove through which the lead wire passes. CONSTITUTION:A lead wire 3 is welded to an object 4 to be welded by the constitution consisting of electrodes 1, 2, the lead wire 3, the object 4 and a groove 5 through which a lead wire passes like in the prior art. Insulating layers 6, 7 are respectively formed on the opposed surfaces of the electrodes 1, 2 and the groove 5 by ''Teflon'' or ceramic coating and calcining or vapor deposition. The welding is consequently accomplished with the smaller diameter of the groove 5 than in the prior art by the presence of the layers 6, 7 and the reacting current making no contribution to welding is eliminated. The resistance heat is thus concentrated on the welding surfaces of the electrodes 1, 2 by which the welding is accomplished satisfactorily.

Inventor: FUJII ATSUHIRO
IPC: C23C16/458
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To improve the resistance to cleaning chemicals while taking measures for the devitrification and cracks by specifying the OH concn. of the quartz surface near wafer supports of a CVD jig. SOLUTION: For manufacturing a CVD jig, the surface is melted using an arc plasma torch 14 e.g. tungsten inert gas torch using a high-m.p. metal e.g. W for high temp. parts of the torch, esp. inner electrode. To avoid contaminating the plasma with a metal from the electrode, an ac electrode is used and covered with a ceramic against sputtering. A wafer support 2 surface is exposed to an atmosphere substd. with Ar gas produced from the arc plasma torch to avoid the action of H on quartz, thereby reducing the OH concn. in quartz to 30ppm or less on the quartz surface to improve the corrosion resistance.

Abstract: PROBLEM TO BE SOLVED: To quantitatively and readily estimate an optical path difference from interference color by a method wherein a scale curve is formed on a phase space in a predetermined number of dimensions on the basis of the relationship between a spectrum distribution obtained from interference color based on the interference of two kinds of white lights and the optical path difference between the two kinds of the white lights and the optical path difference of the two kinds of lights is obtained from a spectrum distribution created by a light of which optical path difference is unknown on the basis of the scale curve. SOLUTION: A characteristic value of a correlation matrix is calculated on the basis of a thirty one-dimensional data vector that is obtained such that 201 pieces of interference colors are made from optical path difference 0nm to optical path difference 1000nm in every 5nm and sampled in very 10nm, thereby obtaining seven base vectors. Since a visually representative space is a three-dimensional one, the above data is indicated on a figure where it is developed on the three-dimensional space designated by the first, second and fourth base vectors. The optical path difference is obtained from the spectrum distribution corresponding to the interference color based on the scale curve formed in accordance with the above method.

Abstract: PURPOSE:To easily change the frequency of an output sinusoidal wave by using a digital signal in plural bits being a memory output so as to control the operation of a D/A converter. CONSTITUTION:A clock pulse outputted from a clock oscillator 1 is counted by a counter 5, a count output signal counted by the counter 5 becomes an address setting signal of a memory 6 and inputted to the memory 6.

The counter 5 starts counting and a control signal operating the D/A converter 8 keeps output in response to the count output signal and the D/A converter 8 outputs a voltage in response to the control signal. Through the consecutive operation, the sinusoidal waveform is outputted from the D/A converter 8. Thus, an output sinusoidal waveform having desired frequency and amplitude is obtained.
